I recently got back into R/C cars and picked up the re-release of the Bruiser I could never afford as a kid. After doing some research I chose a Futaba 3PM-X to get the 3 step switch to control the gear box and 2 Futaba S3010 servos. Not sure if one was necessary for the gear box vs a standard servo. I locked the rear diff and left the front unlocked since I'm probably going to be running mostly in low 4WD or low 2WD. For the ESC I chose a Novak 1835 Eiger 2S/3S Crawling Brushed ESC. I'm leaving the stock motor in for now which is a 540. The last things I need are the battery packs and a charger. I'm not exactly sure what my options are based on my setup. My super old Tamiyas used to run Nicd batteries I believe. I'm interested in getting decent run times longer than 10-15 minutes.
